5 Claims.

The principal object of the present invention is to display to thepublic selected portions of a serial book or magazine in order to makeknown j: the contents of the book, and this is done by putting the bookin show windows or other public places and by mechanically turningselected pages into open position, then closing the magazine or book andafterward again turning the pages 11 and repeating the display.

Other objects of the invention will appear from the followingdescription at the end of which the invention will be claimed.

Generally stated, the invention comprises a fihousing or fittingprovided with means for holding a book at its back in proper positionfor presenting it to View in a show window or other public place; aseries of arms concentrically pivoted in line with the axis of the bookhinge and disposed at the top thereof, the arms being adapted forconnection with selected pages of the book and having lateral extensionsdisposed in overlapping and step arrangement and of which one islongest; a carrier arranged for rotation in two -`directions anddisposed at the pivot of the arms;

a bar slidably mounted on the carrier and provided at one end with aspring linger for progressively engaging the extensions at successiverotations of the carrier in one direction and provided at the other endwith a detent for engaging the longest extension and closing the bookwhen the carrier is rotated in the other direction; tWo sets of rack andpinion mechanisms of which one retracts the bar with a step by stepmotion,

7,-, and of which the other returns the bar to its I "initial position;a driving shaft and reversing apparatus embodying features of theinvention and showing a group of pages as they are being turned.

Referring to the drawings, I is a desk or cabinet and it may bevariously constructed. As shown the top is somewhat inclined andprovided at its margins with spaces in which may be inserted matterdescriptiveof the portions of the book or magazine 2 selected fordisplay. 'Ihe book 2 is supported at its back by suitable clamps 3 asshown in Figure 1A, and its pages are guided by guides 3a. There is aseries of arms 4, 5, 6, 'l and 8 of progressively diminishing lengths,and they are concentrically pivoted at 9 in line with the axis of thehinge of the book 2, and they are disposed at the top of the book. Thesearms are equipped with clamps I0 which are connected to preferably agroup .of pages of the book with the page on top that carries thesubject matter to be displayed. The arms are fitted with lateralextensions II, I2, I3, I4 and I5 disposed in overlapping and steparrangement from the center 9. The extension I is the longest. Thenumber of arms may be increased or diminished and five are shown, butten may be employed and in that case there are ten displays whichcorrespond with the spaces or rulings on the stand at each side of thebook. I6 is a carrier disposed at the top end of the hinge portion ofthe book and arranged for rotation in two directionson an axis which isslightly inclined in respect to the axis'of the arms for a purpose thatwill be presently described. i1 is an operating bar mounted for endwisemovement on the carrier I6. As shown it is mounted in ways I8. The baris provided at one end with a spring finger I9 capable of turning ineither direction and normally held at right angles to the bar. Thespring finger I9 engages the extensions I5 to II on the bars insuccession when the carrier I is rotated clockwise in Figure'5. The barI1 is provided at the other end with a spring pawl 26 effective when thecarrier is turned counter-clockwise in Figure 5 to close the book byengaging the longest extension I5. On the bar I1 are twotoothed racks 2land 22. The rack ZI engages ywith a pinion 23 having teeth all the wayaround its periphery and the rack 22 engages with a pinion 24 having twoteeth, or in other words with a segmental toothed pinion. These pinionsare turnable in respect to a stud 25 fastened to the housing, and theshaft 26 to which the carrier I6 is fastened turns in this stud as abearing. The pinion 24 is permitted to oscillate back and forth on thestud 25 by reason of the centering springs 21 and radial pinion 28, Fig.'7. The pinion 23 is free to turn in one direction but not in the otherdirection. As shown it is internally provided with ratchet teeth 29which Cooperate with spring pressed ratchet bars 30 mounted in the stud25. When the carrier I6 is rotated in l' clockwise direction, (Fig. 5)the two teeth of the pinion 24. push theA rack 22 toward theleft inFigure 1 foreach revolution of the carrier I6 and bar I1 and yrack 22 sothat the finger is retracted l with a stepfby step motion. l The rack 2|and the .pinion 23 may not turn in that direction so that the bar I1 isreturnedto its original position withfa comparatively rapid motion. 3|is a power shaft and it is driven from the motor 32 by a belt and pulley33. 'Ihe power shaft at its end is provided withta star wheel whichdrives the gears 38 drives the carrier I6.

' and breaks contact at 46.

shaft 35 in one direction or the other according to the position of theclutch elements 36 and 31 which are toothed for engagement with the starwheel34. The shaft 35 through speed reducing 26 is a countershaft rwhichis driven from the gearing above referred to.d The clutch elements 36and 31 are spring pressedtoward the right in Figure 9 and restrained bya post 4D and a revolvable wheel 4I notched at 42 for the reception ofthe post. The clutch elements 36 and 31 are splined to the shaft 35 sothat they drive the shaft and may move endwise on it. The core of. thesolenoid 43 operates upon a spring retracted swinging frame 44 providedwith a spring retracted pawl 45 that drives the toothed wheel 4I. Thesolenoid 43 is energized and deenergized by the make and break Contact46 actuated by a camil1 on the shaft 26. The cam follower 48 is pivotedat 49 and. makes Only one of the leads ofthe winding ofthe solenoid isindicated at 5B. The springdetent 5I insures that the turning motion Aofthe carrier I6 is imparted to the pinion 23 inthe proper direction forturning the pinion 23 to shift'the rack 2l and bar I1. Y

'I'lie mode of operation may be described as follows: Assuming that thebook is in closed .position to the right in Figure 1, the cycle ofoperations vin opening further portions of thebook from right to leftmay be explained as follows: 'I'he carrier is turned counter-clockwisein Figure 1, or clockwise in Figure 5 and the end of the bar I1 which istted with the spring finger I9 is in extended position. During the rstrevolution of the carrier the nger engages the extension I5, Figure 3,and turns the pages, for example from 1 to 20, in a group from right toleft. When these pages have been fully turned the spring finger byyielding passes the extension I5 and in doing so assures that the pagesare in fully open position. At the next revolution of the carrier I6 andbar I1 the latter is retracted so that the spring finger engages theextension I4 (as in Figure 6) and turns the group of pages connected tothe bar 1 from right to left. The described operation is repeated witheach o'f the succeeding bars and groups of pages until nally the book isfully open. 'I'he direction of rotation of the carrier I6 and bar I1 isreversed so that it is counterclockwise in Figure 5, and clockwise inFigure 1. The pawl 20 engages the extension I5 and so closes the book toits original position. The angular disposition of the axis of thecarrier I 6 in respect to the axis of the series of bars causes the endof the pawl 20 to slide 01T the extension I5 during the revolution andafter the book has been at least started into closed position. When thebook is being opened the pawl 20 slides idly by the extensions on thebars. The reversal in the direction of rotation of the carrier I6 andbar I1 is effected by the cam 41 and contact 46 which causes theimpulses from the core of the solenoid 43 to turn the toothed wheel 4Ito bring the notch 42 into and out of line with the post 40, therebyshifting the spring'pressed clutch members 36 and 31 to engage eitherone or the other of them with the star wheel 34`on the drive shaft. Thelost motion device shown at 39 (Figure 4) between the wheel 41 and theshaft 26, permits the follower 48, Figure 10, to freely enter the notchin the element 41, and thus provide quick action at 46.

It will be obvious to'those skilled in the art that modifications may bemade in details of construction and in matters of mere form withoutdeparting from the spirit of the invention which is not limited to suchmatters or otherwise than as the prior art and the append-ed claims mayrequire.
